That was a trivial thing in comparison to this, and no man should have to testify about himself in a trial against him. That is a great princible of Freedom. Why say nay to it, which you do in practical effect? If one hews to the another great princible -- that of presumption of innocence -- why then what a man doesn't say sshould be held to speak for him. Your stance is affine to presumption of guilt, which is a stance poison to Liberty.
That is also why there is a law saying YOU CANNOT BE FORCED TO TESTIFY in a trial where you are the defendant.
